The short version: we collect what we need to show you your own energy use, we keep it in the UK, we never sell it, and we never share it with energy suppliers.
ISAIAH LTD, trading as OHMS BI, is the data controller. We are registered in England and Wales, company number 08568513, registered office 15a Seaton Road, Mitcham, Surrey, CR4 3ER.
For anything in this policy, email hello@ohmsbi.co.uk.
| Information | Why we hold it |
|---|---|
| Email address and password | To create your account and let you sign in. Passwords are stored hashed; we never see them. |
| Name, if you give one | To address you properly in emails. |
| Meter readings, tariff rates, billing dates | The substance of the service. Without these there is nothing to calculate. |
| Outward postcode only (for example CR4) | To pick the right Ofgem price cap region. We do not ask for or store your full address. |
| Plan and subscription status | To know what you are entitled to. |
| Basic technical logs | Security and diagnosing faults. |
We do not collect special category data, and we do not build advertising profiles.
Payments are processed by Stripe. Card details are entered on Stripe's own checkout and never reach our systems. We receive only a customer reference, the plan bought, and whether payment succeeded.
The service currently works from readings you enter yourself. We do not collect data from your smart meter.
If automated collection becomes available it will be a separate paid option requiring your explicit, revocable consent, and this policy will be updated before it launches. Consent for that would be specific to the meter points you nominate, and you could withdraw it at any time.
Your account and energy data are stored in the United Kingdom, in a database hosted in the London region.
| Processor | Purpose | Location |
|---|---|---|
| Supabase | Database, accounts and authentication | United Kingdom (London) |
| Netlify | Website and application hosting | United States |
| Stripe | Payments and subscription billing | Ireland and United States |
| Intuit Mailchimp | Waitlist and product emails | United States |
| Google Workspace | Our business email | European Union and United States |
Where a processor is outside the UK, the transfer is covered by the UK International Data Transfer Addendum or an adequacy decision. Each of them acts only on our instructions.
Only the processors listed above, and anyone we are legally required to disclose to.
We do not sell personal data. We do not pass it to energy suppliers, price comparison sites, brokers or advertisers.
Under UK data protection law you can ask us to give you a copy of your data, correct it, delete it, restrict how we use it, or provide it in a portable format. You can object to processing based on legitimate interests, and withdraw consent to marketing at any time.
Email hello@ohmsbi.co.uk and we will respond within one month.
If you are unhappy with how we have handled your information you can complain to the Information Commissioner's Office at ico.org.uk or on 0303 123 1113. We would rather you came to us first so we can put it right.
The application stores a sign-in token in your browser so you stay logged in, and remembers your display preferences. These are necessary for the service to work and are not used for tracking or advertising.
We do not use advertising cookies or third-party tracking pixels on this site.
The service is not intended for anyone under 18 and we do not knowingly collect their data.
If we change this policy we will update the date at the top, and for significant changes we will email account holders.
